Noise From Motors
December 15, 2009
Some of you may remember that I was having a difficult time getting an Arduino Motor Shield to run my 4 wheel motors on my robot Herbert. No matter what I tried, I couldn't get it to work right so I finally decided to try a different route. I bought two qik2s9v motor controllers from Pololu...one board for the front motors and one board for the back motors.
Here's the sucky thing...I'm having the same weird problems I was having with the motor shield...sometimes they work, sometimes they don't...sometimes they work for a second and stop....just weird, whimpy stuff....so this got me to wondering...
Could these be really noisy motors I have and could that make them interefere with the logic on the Arduino? Has anyone experienced anything like that? I'm pretty sure I read somewhere else that electrical noise can cause problems...if so, what's the solution?
As an FYI, I have the Arduino running off a 5 V Minty Boost, the motor controller board running of the 5 volt out on the Arduino and the motors have their own power supply....I'm pretty positive it is not a battery issue...
